Multiple selection

The multiple selection control is a list element in which several entries can be selected at once. For example, it is suitable for distribution lists, article groups etc. Multiple selection is available as an input and view element.

Multiple selection as an input element

Properties in the browser

Data source "Values from applications" / "User-defined values"

If you select the options "Values from applications" or "User-defined values" as the data source in the properties of the multiple selection, the element in the browser consists of two lists. All selectable entries are listed on the left, and all selected entries are listed on the right. The selected entries are stored in the linked data field when the page is saved, provided a link has been configured.

The arrow buttons to the top right or left of the list titles can be used to move the currently selected entry from one list to another. This also works by double-clicking on an entry. You can also select multiple entries by holding down the CTRL key.

The multiple selection can be configured to get its entries from, for example, an ID or GUID but display a different value from the same data group. For example, article numbers could be used as entries and the article description could be displayed instead.

Furthermore, you have the ability to set up a so-called selection filter, depicted by images that you can select freely, which will be shown above the entries. Clicking on an image activates the filter accordingly.

The values entered with a multiple selection can be displayed with the "Multiple selection view" and view table.

Users and groups

If you have selected the "Distributor selection" options as the data source in the properties of the multiple selection, the multiple selection can be used in the browser to select users, user groups and other objects from the "Users" module.

You can search for terms and filter the list of user objects. The data that can be used for the search is defined in the schema manager. Set the "Use in the user administration search" setting for the desired attributes.

The selection filter - filter buttons above the user lists - allows you to restrict or expand the search to users, user groups, distribution lists, organizational units and roles, depending on whether the corresponding button is activated or deactivated.

When you save the data record, the GUIDs of the user objects will be saved to the linked data field. New distribution lists can be defined by clicking on "Create distribution list", provided the "Create distribution list" setting is activated in the data source.

The structure of the user administration is mapped here. Select here where the new distribution list should be created and click "Save".

Provide the new distribution list with a name and description here. The members of the distribution list can be defined underneath. To do this, click on the button on the right.

Select the desired member(s) here and click "Save".

Switch to the "Authorizations" tab.

You can define which users and/or objects from the User Manager will be allowed to change the recently created distribution list. The relevant users can be selected by clicking on the button on the right. After saving, the new distribution list is entered in the "Users" module.

Click on to edit all existing distribution lists.

Properties in the "Applications" module

If you create a multiple selection in the "Applications" module, the properties dialog opens automatically.

General

Here you can set the general properties of the multiple selection.

Title / Title from constant

A static title can be entered here. Alternatively, the title can be obtained from a language constant, which you can select here. All information on this topic can be found here.

Heading "Unselected entries" / Heading "Selected entries"

The titles for both lists in the Multiple selection element can be defined here. A constant can also be used here.

Input required

The element will be made into a mandatory field.

Invalid entries

Display stored values

If values are written to a data field via a multiple selection, the values may no longer be valid, e.g. due to an application export or import. With this setting, these invalid stored values will be displayed instead of the current configured display values.

Delete when saving

Invalid values are removed from the data field of the current data record.

Search options

Initial search expression

The search term entered here is automatically entered in the search field and filters the "Available" list when the corresponding page is loaded. The maximum number of entries is displayed if the character * is entered in the search field.

No search expression shows all entries

Displays all entries when the search field is empty.

Click "Next".

Data source

The source of the entries in the multiple selection is configured here.

Values from applications

With these settings the entries are created from the data of any application.

Application, Data group

Select the application and data group whose values should be shown in the multiple selection.

Filter

Opens a dialog in which a filter can be defined. The data will then be displayed in the multiple selection according to the filter criteria.

Saved value

Here, all data fields from the selected data group will be shown. Specify the field whose values are to be saved when the user selects an entry in the multiple selection. This gives you the ability, for example, to show names of employees in the multiple selection, but to save their ID number instead of the name.

Additional options

Maximum number of entries

The value limits the number of entries. With the value -1, all entries will be shown.

Sort

The fields according to which the entries are currently sorted are displayed here. Click on "Sorting" to open a dialog in which the data fields to be sorted can be selected.

Preview

In the lower part of the dialog, you can see a preview of the list with the current settings for display values and separators.

Users and groups

Instead of the "Values from applications" data source option, the "Distributor selection" setting can also be selected for multiple selection. This means that the element can be used to select users, user groups and other objects from the "Users" module. You can find out here what a multiple selection configured in this way looks like on the web and how it can be used there.

Maximum number of elements in dialog

With this setting, the number of search hits to be shown can be restricted. In the users and groups selection, no additional filters can be defined or changes made to the existing filter settings.

Click "OK" to save changes and close the dialog again.

User-defined values

Instead of the "Value from applications" or "Distributor selection" options, user-defined values can also be used as entries in the multiple selection. User-defined values therefore do not originate from a data source, but are statically entered here in the dialog.

Data type of the stored value

Enter the data type with which the selected value is to be saved.

Displayed value" column

The value entered here will be shown in the multiple selection in the browser.

Create new data field

Opens a dialog in which a new text data field can be created.

Data group

The values of a multiple selection will be stored as individual data records in a subordinate data group.

Selection list "Data group"

If subordinate data groups exist, they can be selected and used here.

Create new child data group

Creates a subordinate data group with the relevant system data fields and an ID field for the ID of the memory value.

The values in the primary key and foreign key created automatically when data records are created in the browser. The value of the primary key corresponds to the ID of a child data record; the value of the foreign key to the ID of the parent data record. The memory value is determined from the data source.

The small arrow symbol to the right of the button displays a menu that can be used to select the type of primary key for the new child data group ("Integer as primary key" or "GUID as primary key").

Grouping filter for saved data records

Opens a dialog in which a filter can be defined that is applied when using multiple selection input elements on an input page. For example, say you use two multiple selection edit elements on one edit page. With the first multiple selection, you will select employees of the call center; with the other multiple selection, employees of the service department, in order to call together a team to take care of a common task.

Data origin" column

For an existing child data group, the data field names will be shown here. If a new child data group is created here, the entry "Automatic determination" is displayed here.

Value" column

Displays the value type stored in the corresponding field.

Data field" column
